Abstract (en)
[origin: EP3711892A1] A first metal member (1) and a second metal member (2) are joined together using a rotary tool (F1D) comprising a base side pin (F3) and a tip side pin (F4), comprising an overlapping and abutting process of forming an overlapped portion (J1a), a top side abutted portion (J1b) and a back side abutted portion (J1c), and a friction stirring process of inserting the tip side pin (F4) that is rotating into the top side abutted portion (J1b) to join the top side abutted portion (J1b) and the overlapped portion (J1a) with a flat face (F5) vertical to a rotation axis of the rotary tool (F1D) being in contact with both the first metal member (1) and the second metal member (2) and with a tip face (f7) of a protruding portion (F6) protruding from the flat face (F5) being inserted deep over the overlapped portion (J1a).
